Geeks: We've Got Your Number

Regular numbers? Those are for amateurs. Bring your inner genius out for all to envy with a smart and stylish watch that features the equivalent notation of each number.

For nascent mathematicians and victims of the occasional memory lapse, a cheat sheet is included with each watch.:
1: i is equal to the square root of -1, so i^2= -1. The absolute value of -1 is 1.
2: This represents 2 in binary code.
3: The cube root of 27
4: 11 base 3, which represents 4 in the ternary system
5: Log(20x)=2 is equivalent to 20x=10^2 or 20x=100, where x=5.
6: Euler's product formula: phi(p^k)=(p^k)(1-(1/p)), where (p^k)=9
7: This is a binomial coefficient, so with the formula n/k = (n!)/((k!)(n-k)!), n/k=7.
8: This is a natural logarithm where ln(e^x)=x, so ln(e^8)=8.
9: This summation is equal to 3(1)+3(2)=3+6=9.
10: Since clocks "wrap around" every 12 hours, the hour number starts over after it reaches 12. This is arithmetic modulo 12. 10mod12 is 10:00, and 16mod12 would be 4:00, for example.
11: B'L is Legendre's constant, which is equal to 1, so this equation becomes the square root of 121, which is 11.
12: Hexadecimal representation of 12

Didn't get to give it as a gift

Comments about UncommonGoods Equation Geek Watch:

I bought this as a gift for a birthday and graduation in college for a friend I liked. She never received it and because of that I didn't open it. I still think it's great and rather my fault for not being good enough.

    From the picture, I was worried that the strap would be a bit stiff or hard. But turns out it was very soft! The watch's crystal has a nice shine as well. Overall, the product is great, and I'd want to buy a second one for myself!

    Got this watch in black for my son for xmas (2 years ago)...he absolutely loves it. It's stylish and unless someone looks at it closely (which they do), they don't realize it has equations on the face. So subtle. So stylish!

        Comments about UncommonGoods Equation Geek Watch:

        This watch was absolutely adored when I gave it as a gift for my husband who's a math wiz. It's unusual in a good way, which make the gift special to the person who is the receiver. Unfortunately, he apparently had too sensitive of skin, and broke out in a rash (I'm sure that's not normal for most people) so we're a little at a loss now as he has a watch he can't wear. But it's nice to look at.....

          When I ordered the watch, it was backordered for 6 weeks so I had to IOU my son on his birthday. The first one I received broke after 1 week. I sent it back and there was confusion about the fact that I wanted a replacement not a refund. After that was sorted out (customer service was great!)the second one arrived the next day. My son loves it and it seems to be well made. Hopefully this one will last more than a week or two!

              Gave this to a grandson for his birthday. He is an engineering student and loved the watch. It looked great on his arm. Masculine enough. I'm thrilled that he is thrilled.

              Looks good. This is a gift to a grandchild math whizz. I will let him review it after I give it to him in June at his graduation.
              It is presented well and looks novel.

              Watch is great, I bought 2. One for self and one as a gift. The tin the watch came in was dented, had to rewrap prior to gifting. Both tins were dented, but merchandise works great.
